Dodge Challenger Hellcat & Redeye Tuning
Dodge Challenger Hellcat & Redeye Remote Custom Tuning with HP Tuners
N2 Speed builds custom HP Tuners calibrations for the Dodge Challenger Hellcat & Redeye and its supercharged 6.2L HEMI V8 — remotely, so your Challenger never has to sit on someone else's dyno for a week. Every file is written for your specific combination of modifications, fuel and driving use. We do not resell generic canned maps.
Tuning is handled by email and data log review: you send us your stock file and vehicle details, we build the calibration, you flash it with your HP Tuners interface, then we refine it from your logs until the supercharged is exactly where it should be.

- 2015-2018 SRT Hellcat — 707 hp, 2.4L IHI supercharger, ZF8HP or 6-speed manual

Common supporting modifications we tune around include upper and lower pulley, ported blower snout, long-tube headers, upgraded heat exchanger, E85 or flex fuel, larger injectors, nitrous.

HP Tuners Credits for the Dodge Challenger Hellcat & Redeye
Total Credits Needed
Credits are how HP Tuners licenses each vehicle. They load onto your MPVI4 and are spent once, the first time the module is read. Adding transmission tuning means a second module is licensed, so the credit total goes up — the options above already include both.
- Engine Only — 2015-2023: 2 Universal Credits
- Engine and Transmission — 2015-2023 ZF8HP 8-speed: 6 Universal Credits
Manual transmission? There is no transmission control module to calibrate, so choose Engine Only and select not applicable under Transmission Tuning.
Credit requirements are set by HP Tuners and can change with model year. If your car is not listed exactly, send your VIN to sales@n2speed.com and we will confirm before you buy anything.
What Every Tune Includes
- A custom calibration written for your supercharged 6.2L HEMI V8, modifications and fuel
- Optimized fuel, spark and torque management tables

How Remote Tuning Works
- Order your stage. Pick the package that matches your build.
- Send your information. Email your VIN, mod list, fuel type and stock read to sales@n2speed.com.
- Flash the file. We email your calibration, normally within 1-2 business days.
- Log and refine. Send data logs; we revise until the supercharged is dialed in.
Revision turnaround: Revisions are done in the order they are received during business hours. Set time frames are available with notice. After-hours and weekend revisions are done when available.
Locked Challenger PCMs
Stellantis locks the PCM on 2015 and newer Dodge, Chrysler, Jeep and RAM vehicles against aftermarket writing. If your Challenger cannot be flashed through the OBD-II port, we handle it with our mail-in Dodge, RAM & Jeep PCM unlock service, and we also offer Dodge PCM bench tuning service for modules that need to be written on the bench. Send your VIN and we will confirm which route yours needs before you spend anything.
Frequently Asked Questions
How much does a Dodge Challenger Hellcat & Redeye tune cost?
Our Dodge Challenger Hellcat & Redeye HP Tuners remote tunes are $450 for Stage 1 (stock and bolt-on builds), $550 for Stage 2, and $650 for Stage 3 supercharged, turbocharged or nitrous builds. Pricing includes revisions after we review your data logs.
How much horsepower will a tune add to my Dodge Challenger Hellcat & Redeye?
On 93 octane a Stage 1 calibration typically returns 30-50 hp on 93 octane with the factory blower and pulley. Stage 2 builds see 80-130 hp with a pulley, headers and supporting bolt-ons, and Stage 3 builds see 200-350+ hp on E85 with a pulley or blower upgrade. Actual results depend on your modifications, fuel quality, altitude and ambient temperature.
Do I need to unlock my PCM before tuning?
Yes. Every Dodge Challenger Hellcat & Redeye has a factory-locked PCM, so it must go through our mail-in Dodge, RAM & Jeep PCM unlock service before HP Tuners can write to it. We handle the whole process.
How many HP Tuners credits do I need?
- Engine Only — 2015-2023: 2 Universal Credits
- Engine and Transmission — 2015-2023 ZF8HP 8-speed: 6 Universal Credits
What equipment do I need for remote tuning?
An HP Tuners interface — we recommend the HP Tuners MPVI4 with Pro Feature Set — the credits for your vehicle, a Windows laptop with VCM Suite installed, and an internet connection. A wideband air/fuel gauge is recommended for Stage 2 and required for Stage 3. You can add the interface and credits to your order.
How long does the tuning process take?
Your first calibration is normally emailed within 1-2 business days of us receiving your vehicle information and stock file. Revisions are done in the order they are received during business hours. Set time frames are available with notice. After-hours and weekend revisions are done when available.
Can you tune a completely stock Dodge Challenger Hellcat & Redeye?
Yes. A stock supercharged 6.2L HEMI V8 still leaves power, throttle response and transmission behaviour on the table. Stage 1 is designed exactly for stock and lightly modified vehicles.
Will a custom tune affect my factory warranty?
Modifying the factory calibration can affect powertrain warranty coverage. We recommend returning to the stock file before any dealer visit. Full terms appear on each product page.
